Application; filed April 18,

My present invention comprehends a, novel construction and arrangement of a.- projecting lantern which is especially'adapt- ,ed to beemployed to project. in a desired.

direction, the representation of a. picture,

Rdrawing, statue, or other solid objectso that it can be reproduced. i

:It further comprehends a novel lantern.

whereinthe objectionalheat of'the lamp is .overcomeby forming the casing of a front-'- wall and two hinged sides. 1

It further comprehends novel lamp-supports, novel means for adjusting reflectors, inovelmeans for mounting a mirror, a novel construction of an adjustable support forthe picture or article to be projected,-andnovel means for supporting a cover.

Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description and the appended claims. 7 j

For the purpose of illustrating the invention, Ihave shown in theaccompanying drawing atypical embodiment'of it, which,

in practice,.wi1l give reliable and satisfactory .results. It is however to be understood that this embodiment is typical only and that the various instrumentalities of which my invention consist can be 'variouslyarranged and organized, and that: the; invention is not limited to the precise arrange-j ment'and organization of these instrumentaliti'es as herein set forth.

Referring to the drawings:

1 designates a projecting lantern, embodying my invention. Instead ofemploying a closed casing or cabinet which becomes highly heated due to the light from the lamps, the casing consists of a front wall 2 to which are secured by means of the hinges 3, the side walls 4. The front wall 2 is provided with the guides 5, in which are vertically adjustable the angle bars 6. 7 designates a lens holder slide which engages 1924. ;Serial No. 707,352;

The object which is to be projected such as a photograph or picture, is secured on the object holder 27 as will be understoodby reference to Figure '2. A solid object suchas a; statue, or an inanimate or animate object is placed in the same relative position with respect to the lens as is the object 33.

The lamps 13 are illuminated, and the reflectors 17 are adjusted so that the light rays will pass to the obj eet; andt therefrom to the dens .36 sand to-the mirror 23 which latter reflects the light rays on to any des ired surface, S0 thahtheyflilhbe .visih eto the operator, and sothat,if desired, the representation projected can be outlinegL eolnred;
